no sound on ubuntu hardy

The laptop I have is a Asus m50vm-a1. I've tried to configure my alsa-base in all possibilities but I still have no sound whatsoever. my aplay -l reads

Code:

**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: HDA Generic [HDA Generic]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

cat /proc/asound/card0/codec#* | grep Codec outputs ...

Code:

Codec: Realtek ID 663
Codec: LSI ID 1040
Codec: Generic 10de ID 6

so far, I've already tried all the drivers that's listed under ALC662/663 in one of the alsa files. So far, I've had no luck for the last two weeks or so and it's getting beyond frustating. Any help would be awesome before I scrap my linux partition

 

Here's what I've got in my Asus that works OTB:

Codec: Realtek ALC883
Codec: Generic 1543 Si3054

I'll check for you.

 

have you tried running 'alsamixer' to make sure you don't have volume muted? it will have 'mm' on the mixer control. also, make sure your volume applet has all the controls you see in alsamixer that you need to adjust volume.

edit: i just noticed you're running hardy which comes with pulseaudio by default so you should really be looking at your sound preferences instead of aplay. have you tried setting your sound playback to pulseaudio?

 

Since your laptop hardware is so new, you unfortunately might not get sound support until there are updates to the alsa driver. The only thing you can do is make sure you're up to date on the latest version of alsa, 1.0.17,. You seem to indicate that you've tried various configurations by adding the line;

Code:

options snd-hda-intel model=[model_name]

to your /etc/modprobe.d/alsa-base config file, and using the following model names;

Which is correct since you have the Realtek 663. As a long shot I might try using some config options from others, like this user's post on installing Ubuntu on his Asus M50Sv-A1. His alsa config line was;

Code:

options snd-hda-intel model=haier-w66

Other than that your best bet is to subscribe to one of the alsa mailing lists and get your information to the alsa developers so that they can include support in a future release. You may want to check out the alsa debug script Aadebug, as it will correctly grab all information needed by the alsa devs.

Good Luck..
